BRIDGEPORT -- Police are asking the public's help in finding a gunman who robbed the Subway sandwich shop at 2835 Fairfield Ave. on Tuesday night.

The same man may have been involved in a similar robbery a short time later in Milford, officials said. Although he wore a mask when he entered the restaurant here, shortly before 9 p.m., he took it off, allowing the video camera to capture clear images of his face, police said.

The robber of the Quick Stop at 186 Bridgeport Avenue, about 45 minutes later, kept his mask on, said Officer Jeff Nielsen, the department's spokesman.

In both cases, the robber was described as black, carrying a silver handgun and driving a silver car with blue LED-style headlights. At the Milford convenience store, the robber brandished the gun and demanded money from the clerk.

Milford police said witnesses told them that the robber is about 5-foot-8, 140 pounds, and was wearing a black hooded sweatshirt, black jeans, black sneakers and a black mask covering part of his face.

Detectives from the two police departments have reviewed the video from the Bridgeport holdup and believe they are seeking the same man, officials said.

Anyone with information regarding the Milford incident is asked to contact Detective Thomas Bassett at 203-783-4727 or email tbassett@ci.milford.ct.us.

A witness told Bridgeport police that the robber's car was a 1996-2000 white Acura CL. Anyone with information on the Subway robbery is asked to contact Detective Michael Fiumidinisi at 203-581-5246.
